| Abstract(in English) | In LTE-Advanced, a terminal can transmit signals simultaneously from 4 antennas, while an LTE terminal transmits a signal from only a single antenna. In LTE-Advanced standardization, antenna-specific sounding reference signal (SRS) transmission is considered as baseline for SRS transmission, but a single precoded SRS transmission based on channel reciprocity has potential capability of improving system performance in TDD systems. In this paper. We compare the performance of the two SRS transmission schemes. Simulation results show that the precoded SRS transmission provides 2 or 3dB higher gain than antenna-specific SRS transmission in multiuser MIMO systems. |
